1 Claim. i

This invention relates to cry-acetylene equipment fo welding with acetylene and oxygen gases. Such an outfit requires a bottle of each gas and a hose running from each bottle to a welding torch. In large shops, garages, etc., it is necessary to either take the work to the outfit or to drag the hoses over the floor where they become entangled and damaged. Portable welding devices require the hose to be Wound on suitable receiving posts or the like on a truck or other vehicle carrying the outfit. It is clifficult to wind the hoses on the posts and they often become kinked and damaged.

The principal object of this invention is to provide an automatic hose reel for oxy-acetylene hoses which will automatically reel in the unnecessary slack. in the hose; which will completely reel in the hoses when the device is not in use; and in which there will be no possibility of gas leakage.

Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and eificiency. These will become more apparent from the following description.

In the following detailed description of the invention, reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description.

In the drawing:

Fig. 1 is a side View of the improved oxy-acetylene welding outfit;

Fig. 2 is a plan View thereof;

Fig. 3 is an enlarged vertical section taken on the line 3-3, Fig. 2;

Fig. 4 is a similarly enlarged horizontal section taken on the line 4-4, Fig. 3; and

Fig. 5 is a detail, fragmentary, sectional View, taken on the line 55, Fig. 3.

The improved oxy-aoetylene outfit is mounted upona suitable base plate II! which may be mounted on any desired supporting structure such as skids 38. An upright pedestal II, is secured to the plate II) in any desired manner such as by means of a threaded attachment stud I2 and a clamp nut I3. A vertical pivot post I 4 is formed on the pedestal I I and arises axially therefrom. The pivot post is of less diameter than the pedestal so that a shoulder is provided at the top of the latter.

The shoulder supports suitable thrust bearings I5 upon which a tubular sleeve IE rests. The sleeve I6 rotatably surrounds the post I4 and it is supported vertically thereon by means of an upper radial anti-friction bearing IT. The hearing ll surrounds a bearing stud I8 formed on the top of the post I4 and is held in place thereon by means of a bearing nut I9. A rotatable tube 2!] is formed on and about the sleeve I 6 as an integral part thereof.

A circular reel plate 2| is welded or otherwise attached to and about the lower extremity of the tube 28. A cylindrical hose drum 22 is aflixed to and extends concentrically downward from the reel plate 2I terminating in a bottom reel flange 23. Thus, the entire structure, consisting of the tube 20, the reel plate 2|, the hose drum 22, and the reel flange 23, rotates freely about the axis of the post I l supported by the bearings I5 and I1.

The reel plate 2! is provided with two bottle cups 2 and 25 which are hinged to the plate 2| by means of suitable hinges 26. The cup 24 is designed to support an oxygen bottle 21 and the cup 25 is designed to support an acetylene bot tle 28. The bottles 21 and 28 are held in fixed relation to the vertical tube 26 by means of annular straps 29. The straps 29 are of a size to snugly surround the bottles and are removably attached to the tube 2! by means of separable attachment clips 30 which can be separated by withdrawing removable locking pins 3|.

The bottles 21 and '23 are provided with the usual pressure reducing valves 32 from. which flexible hoses 33 and 34 lead through suitable openings in the plate 2! and are wound about the hose drum 22 between the reel plate 2i and the flange plate 23. The free extremities of the hoses 33 and 34 extend between guide sheaves 35 rotatably mounted in a sheave bracket 36 on the base plate 18. The hoses terminate in a con-- 7 ventional welding or cutting torch 3i.

When it is desired to use the torch 3'! it is sim-- ply carried to the job. This causes the hoses 34 and 36 to unroll from the reel drum 22! rotating the entire mechanism including the bottles 21 and 28, about the pivot post It.

The hoses are reeled back upon the reel drum 22 by means of a flat coiled spring 39 which surrounds the pedestal II within the drum 22. This spring is similar to the usual clock spring except on a much larger scale. One extremity of the spring 39 is permanently attached. to the pedestal II by means of suitable attachment screws 40. The other extremity is secured to the inside of the drum 22. The spring is so arranged that when the hoses are withdrawn it will be wound and when the hoses are released it will unwind and rotate the entire apparatus.

The reel drum is prevented from rotating under the influence of the spring by means of a latch pawl 4| which engages suitable ratchet notches 42 in the periphery of the flange plate 23. The latch pawl 4! is constantly urged against the peripheral edge; of the flange plate 23 by means of.:a=suitable spring 43.

While a specific form of the improvement has been described and illustrated herein, it is de sired to be understood thatvthe same may be varled, within the scope of the 'appendedic1aim;..with! out departing from the spiritof? the invention:
